  • Automated voltage control oscillator tuning
    Patent number: 6407645
    Abstract: There is disclosed a first stub short bonded across conductive runners of a tuning stub at a distance preferably greater than a distance resulting in the desired frequency of operation of a voltage controlled oscillator tuned by the tuning stub. Thereafter, the voltage controlled oscillator is powered and tested to determine the frequency of operation of the voltage controlled oscillator. The position of a second stub short is determined based on the frequency of oscillation of the oscillator due to the presence of the first stub short, the geometry of the tuning stub and the desired frequency of operation of the voltage controlled oscillator. A second stub short is precisely positioned along the stub using automated equipment, relative to the position of the first stub short, to result in the desired frequency of operation of the voltage controlled oscillator.
